The utility model system is about in cassette recorder, the ejector for recorder tape cassette of rocking in order to the tape cassette holder that prevents when not loading tape cassete.

Fig. 4 to Figure 13 shows that the summary of the cassette recorder of previous exploitations such as creator of the present utility model constitutes, and it proposes patented claim special former clear 59-15676 number with (Japan), and this is known person.

That is, Fig. 4 is the planimetric map in halted state, is adorning tape transport mechanism at the upside of main substrate 1, and this mechanism comprises each a pair of spool 2a, 2b, capstan 3a, 3b, and rotation drives the motor 4 of this capstan 3a, 3b.Motor 4 is given the direction rotation with seasonal two capstan 3a, 3b towards its tape separately, and makes the tape coiling direction rotation separately of its court in a pair of spool 2a, 2b alternatively.

Again, on main substrate 1, adorning the magnetic head 5 that playback is used, and pinching roller 6a, 6b corresponding to each capstan 3a, 3b.

Again, on main substrate 1, be provided with rotor plate 8, this rotor plate 8 with the last ora terminalis among Fig. 4 serve as axle and can be along the vertical direction the direction of the paper orthogonal of Fig. 4 (that is with) freely rotate: the pivoting end support at this rotor plate 8 has tape cassette holder 9, and this tape cassette holder 9 also can be along the vertical direction (be among Fig. 4 with the direction of paper orthogonal) freely rotates (with reference to figure 8, Fig. 9).Again, the binding structure of rotor plate 8 and tape cassette holder 9 is as shown in figure 13, makes the top joggling part 9a of tape cassette holder 9 be embedded in the 8a that cracks of rotor plate 8 by the below, and makes the top engaging of leading section 8b of the hook-shaped joggling part 9b autorotation plate 8 of tape cassette holder 9.

The amount of spin towards the top of rotor plate 8 be subjected to main substrate 1 the warpage sheet 10 of side wall upper part limit because the existence of this warpage sheet 10, when rotor plate 8 and tape cassette holder 9 are mobile towards the top, promptly remain on state with main substrate 1 almost parallel.

The lower end side (or left end side in Fig. 8) of tape cassette holder 9 in Fig. 4 is provided with tape cassete and inserts extraction mouth 11,, when tape cassete inserts the state shown in Figure 4 of extracting the position out, can insert by this tape cassete and extract mouthfuls 11 out and make tape cassete 12 insert or extract out 9 of tape cassette holders.And when the state that tape cassete 12 inserts in the tape cassette holder 9, be as shown in Figure 9, rotor plate 8 rotates towards the below, and when 9 what tape cassetes of tape cassette holder loading position (being operating position), tape cassete 12 promptly engages what spool 2a, 2b and capstan 3a, 3b.

Insert to extract the position out when move the tape cassete loading position when tape cassette holder 9 by tape cassete, promptly the left in Fig. 4 moves magnetic head 5 with its interlock, enter as shown in Figure 5 in the tape cassete 12, and with the contact with tape of inside.Again, with this action in magnetic head 5 enters tape cassete 12 interlock mutually, with spool the same sides of motor 4 driving sides pinch roller just across tape and the crimping what pinches the capstan of roller corresponding to this.For example, when spool 2b is activated, pinches roller 6b system and be crimped on capstan 3b across tape.So, tape is driven and is advanced towards a direction, records or the playback action.

Spring bear member 13 prop up in the mode of pivot 14 by an end and be contained in free to rotately rotor plate 8 above.Again, can deviate from the liftout attachment 15 that direction (being the above-below direction among Fig. 4) is free to slide along the insertion of tape cassete 12 also is contained on the rotor plate 8.

This liftout component 15 is as shown in Figure 8, has abutting part 16 at one end (upper end in Fig. 4), the tape cassete 12 that is inserted in the tape cassette holder 9 is connected to this abutting part 16: and have engaging claw 17 at its other end, this engaging claw 17 is fastened on a side's who is inserted into the tape cassete 12 in the tape cassette holder 9 propeller boss hole: and be provided with teat 19 above the liftout component 15 at this, this teat 19 is connected to the bulge 18 of the rotation ora terminalis that is formed on the rotor plate 8, and the restriction tape cassete pushes back the amount of movement of direction.

On the one hand, the spring rotation end system of bearing member 13 disposes towards liftout component 15 sides.And bear between the rotation end of member 13 at liftout component 15 and spring, have contact with to have and open the ejector spring 20 that spring constitutes by expansion.

Again, side is provided with tabular card and ends member 21 below rotor plate 8, and it is to be contained in spring to bear on the common axle 14 of member 13 that this card ends member 21 free to rotately.This card ends member 21 to have: butt sheet 22, on the actuating wire of position what liftout component 15: and fastener 24, the erected piece 23(that optionally is sticked in main substrate 1 is with reference to figure 9), tape cassette holder 9 cards are only inserted on the position at tape cassete.By not shown spring and often rotate elastic force towards fastener 24 cards being ended give this fastener 24 in the direction of the side plate upper limb of main substrate 1.

Side plate outside at main substrate 1, system is as Figure 10, shown in Figure 11, be equipped with and eject control member 25, this ejects control member 25 can have in the holding section 26 that front position is bent to form along freely advance and retreat, eject control member 25 with left and right directions among the figure, and bears member 13 via pitman 27 with spring and be connected.Again, this one eject that control member 25 is borrowed back-moving spring 28 and often right-hand in Figure 10 be subjected to the elastic force given.And when this one eject control member 25 as Figure 10, Figure 11, be subjected to back-moving spring 28 effect and when right-hand (direction resets) is mobile, make spring bear member 13 as Fig. 4, Fig. 5 toward the clockwise direction (direction of reversing) move: if as shown in Figure 12, make to eject control member 25 antagonism back-moving springs 28 and this ejects control member 25 toward the left push operation, then spring bear member 13 also simultaneously towards as Fig. 6, counter clockwise direction (direction moves onward) rotation shown in Figure 7.

The side plate of main substrate 1 outside more Figure 10, shown in Figure 11 eject control member 25 below, tabular operating physical force is housed passes on member 29, the latter can freely advance and retreat along the left and right directions among Figure 10, Figure 11.And this operating physical force passes on member 29 to be subjected to back-moving spring 30 towards the right-hand elastic force of giving often.Operating physical force passes on member 29 as shown in Figure 12, ejecting control member 25 when left moves, bears the pressing force that this ejects control member 25 by compression zone 31, moves towards left integratedly and eject control member 25 with this.Pass on member 29 to be bent to form snap-latch piece 33 at this operating physical force again.

In the side plate of main substrate 1 outside, be fulcrum and tabular linkage part 34 is housed free to rotately with axle 35 ejecting anterior position (the left position in Figure 10) that control member 25 and operating physical force pass on member 29 again.This linkage part 34 has: connecting pin 37, be sticked in the long ditch 36 of the side plate that is located at rotor plate 8: pressed sheets 38, be connected to the holding section 26 that ejects control member 25 by the right side among Figure 10, bear the pressing force that back-moving spring 28 is given birth to: and engaging teat 39,40, the front and back that position what operating physical force is passed on the snap-latch piece 33 of member 29.The rotation elastic force that linkage part 34 is counterclockwise given in Figure 10 by pressing spring 41 by tape cassete often.

Secondly, its action is described.Fig. 4, Fig. 8 and Figure 10 are the states that shows when not loading tape cassete, and under this state, liftout component 15 moves towards the tape cassete removing direction because of the elastic force of ejector spring.Again, tape cassette holder 9 is positioned at the stop position that leaves from main substrate 1, and the fastener 24 that card ends member 21 is sticked in the erected piece 23 of main substrate 1, and stops tape cassette holder 9 moving towards operating position.To bear member 13 be by pitman 27 to spring and eject the elastic force that control member 25 bears back-moving spring 28 again, therefore moves towards the direction of reversing (ejector spring 20 be subjected to deformation direction).On the one hand, make operating physical force pass on the snap-latch piece of member 29 to be connected to the engaging teat 40 of linkage part 34.The homing action that prevention produces because of back-moving spring 30.

Again, linkage part 34 bears back-moving spring 30 and the tape cassete elastic force by pressing spring 41, make tape cassette holder 9 be given rotation elastic force with engaging of connecting pin 37 by long ditch 36, but be subjected to stoping (with reference to figure 4) because of erected piece 23 and engaging of fastener 24 towards the rotation of this direction towards the direction that moves toward operating position.

At this, tape cassete 12 is inserted removal outlet 11 by tape cassete insert in the tape cassette holder 9 towards longitudinally and with rough and main substrate 1 parallel state, then at first the engaging claw 17 of liftout component 15 engages the spool hub bore of what tape cassetes 12.Then, tape cassete 12 pushing is positioned at the abutting part 16 of the liftout component 15 on the insertion line of tape cassete 12, so liftout component 15 is resisted ejector spring 20 then and moved onward.

Along with moving onward of liftout component 15, the elastic deformation amount of ejector spring 20 increases gradually, in case surpass the position of its elastic deformation amount's maximum, the elastic force that then changes over ejector spring 20 is to make liftout component 15 move and act on towards the direction that moves onward.Therefore, do not need power that tape cassete 12 is pressed into, by the elastic force of ejector spring 20 and tape cassete 12 is drawn in the tape cassette holder 9.

Then, liftout component 15 is connected to the butt sheet 22 that card ends member 21, make card only member 21 towards with the counter-rotation of giving elastic force.Therefore, card ends the fastener 24 of member 21 and throws off (with reference to figure 5) from the erected piece 23 of main substrate 1, rotor plate 8 and linkage part 34 bear back-moving spring 30 and tape cassete rotates towards the below by the elastic force of pressing spring 41, tape cassette holder 9 also descends, and makes tape cassete 12 be sticked in spool 2a, 2b and capstan 3a, 3b(with reference to figure 9).

Fig. 5, Fig. 9 and Figure 11 show filling tape cassete state, and promptly tape cassette holder 9 is positioned at the state of operating position.Under this state, because the rotation of linkage part 34, operating physical force passes on the snap-latch piece 33 of member 29 to satisfy by 40 disengagements of engaging teat, and operating physical force passes on member 29 to reset by back-moving spring 30.

Again, the elastic force of back-moving spring 28 is borrowed and the pressed sheets 38 of pushing linkage part 34 in the holding section 26 that ejects control member 25, and this pressing force works and linkage part 34 is rotated towards counter clockwise direction shown in Figure 11.

On the one hand, though the elastic force of ejector spring 20 is passed on towards ejecting control member 25 via pitman 27, this elastic force is also same with back-moving spring 28, acts on ejecting control member 25 towards right-hand, and linkage part 34 is acted on towards counter clockwise direction.

Again, with mobile phase connection, motor 4 startings of tape cassette holder 9 towards operating position, spool on one side for example spool 2b begins to rotate towards certain direction with two capstan 3a, 3b, magnetic head 5 moves and contacts with magnetic head towards the direction of tape cassete 12 simultaneously, and the spool of a side that bears the revolving force of motor 4 is crimped on corresponding capstan 3b with the roller 6b that pinches of the same side across tape, forms recording or tone playing state whereby.

Secondly, when stopping or implementing the situation of taking-up of tape cassete 12, need only to be pressed into as shown in Figure 6 and eject control member 25.When this occasion, ejecting control member 25 is compression zones 31 of the member 29 of pressing operation power reception and registration as illustrated in fig. 12, makes operating physical force pass on member 29 to move towards equidirectional.Therefore, snap-latch piece 33 pushes the engaging teat 39 of linkage parts 34 and makes linkage part 34 rotate toward the clockwise direction as shown in Figure 12.Therefore, rotor plate 8, so tape cassette holder 9 rises to stop position and is extracted from spool 2a, 2b and capstan 3a, 3b tape cassete 12 towards counterclockwise rotating towards the top.

Again,,, make spring bear member 13 as shown in Figure 6, rotate in the counterclockwise direction, ejector spring 20 is reversed by pitman 27 by the push operation that ejects control member 25.Therefore, liftout component 15 bears the elastic force of ejector spring 20 and moves towards the tape cassete removing direction as shown in Figure 7, and its teat 19 is connected to the bulge 18 of rotor plate 8, tape cassete 12 is inserted removal outlet 11 from tape cassete push back.Again, card ends member 21 makes its fastener 24 be limited to the erected piece 23 of main substrate 1 because of spring force resets towards the clockwise direction among Fig. 7, and tape cassette holder 9 is remained in stop position.In case decontrol and eject control member 25, then this member 25 becomes as Fig. 4, Fig. 8 and state shown in Figure 10 promptly because of the effect of back-moving spring 28 resets.

In above-mentioned known devices, by what tape cassette holder 9 are rotation edge portions that twelve Earthly Branches free to rotate are held in rotor plate 8, so when for example this device being used as Car Stereo, do not loading under the state of tape cassete, tape cassette holder 9 rocks because of the vibration of automobile, strikes against the sound that adjoining members sends " Ka Dakada ".With the occasion of this device, also send same sound because of external vibration as the use of portability type again.The unusual sound equipment of this kind is not only unhappy, and may be mistaken as fault, becomes big problem in practicality.

If tape cassette holder 9 rocks, the position of tape cassette holder when the non-filling state of tape cassete can not be certain again, thereby the position of position of causing tape cassete to insert to take off mouthful and tape cassete is inconsistent, the thing that tape cassete also might take place to load.

So the purpose of this utility model, provide a lift cassett off device, in the sound-track engraving apparatus of the pattern of the rotation edge portion that the tape cassette holder is supported in free to rotately rotor plate, be not filled with under the state of tape cassete, even be subjected to external vibration, the tape cassette holder does not also rock, and can often load tape cassete really to eliminate unusual sound equipment.

The utility model is in order to achieve the above object, it is characterized by, on the some of tape cassette holder, be provided with occlusion part, this occlusion part is used for limiting the amount of movement towards the tape cassete removing direction of a liftout component: and this liftout component is to move in order to be subjected to tape cassete pushing when tape cassete is inserted the tape cassette holder, is in order to tape cassete is pushed back to removing direction when mobile in the opposite direction again.

According to ejector for recorder tape cassette of the present utility model, be not load under the state of tape cassete, liftout component is connected to the occlusion part of position on the tape cassette holder, whereby mode and make the tape cassette holder remain on stable status.

Below, an embodiment of the present utility model is described referring to figs. 1 to Fig. 3.Itself and the difference of the existing device that adopts the illustrated mistake of Fig. 4 to Figure 13 only are described.At first, make the abutting part 16 of liftout component 15 form butt sheet 42 towards the side prolongation.On the one hand, be provided with occlusion part 43 in tape cassette holder 9 sides, when the tape cassete removing direction moved, above-mentioned butt sheet 42 was connected to this occlusion part 43 at liftout component 15.This occlusion part 43 is to be used for limiting the amount of movement of liftout component 15 along the tape cassete removing direction.Promptly, when not loading tape cassete, can not resemble that the teat 19 of liftout component 15 is connected to the situation (with reference to figure 3) of the bulge 18 of rotor plate 8 the existing device, but limit the amount of movement of liftout component 15 in the tape cassete removing direction by occlusion part 43.

According to this structure, when not being filled with the state of tape cassete 12, be as shown in Figure 2, the butt sheet 42 that extends towards the side of the abutting part 16 of liftout component 15, by the elastic force of liftout component 15 being given the ejector spring 20 of elastic force towards the tape cassete removing direction, be connected to the occlusion part 43 that is located at tape cassette holder 9 and tape cassette holder 9 bumped, suppress the rotation of tape cassette holder 9.Therefore, tape cassette holder 9 can not resemble and shake for external vibration the existing device, and stops the generation of unusual sound equipment.

According to the utility model, then do not give birth to and rock not loading tape cassette holder under the state of tape cassete, and can prevent the generation of unhappy unusual sound equipment, again under the non-filling state of tape cassete, it is often consistent with the position of tape cassette holder that tape cassete is inserted the position take off mouthful, can go the filling of tape cassete really.
